I just installed Linux Mint 13 x64 Cinnamon yesterday.
As such, it's a pretty fresh install, with a few applications installed on top, but I've been getting random freezes every so often.
I can't identify any particular thing which causes the freeze - it seems to be fairly random. If I were to make a guess, it does seem to happen only when I'm interacting with the machine - that is, I can leave it doing a task for a few hours and it won't freeze up.
I've also just been using Windows 7 in VirtualBox (running on top of LM) for quite a while and not had any issues - so it _seems_ that the issue may be something to do with interacting with stuff in the Linux environment.
By "freeze" I mean a complete system lock up. The mouse won't respond, the numlock/capslock/scroll lock LEDs won't toggle on the keyboard when the respective key is pressed. Key combinations like Ctrl+Alt+Del, Ctrl+Alt+F2, Alt+SysReq+I etc have no effect. The system won't respond to USB drive insertions or the power button being pressed, so I need to hold down the power button to get the machine to turn off.
If music happens to be playing in the background, the last ~0.5 secs will just constantly keep looping whilst frozen. (but music isn't the cause as this has occurred when no music player is open)
My hardware is as follows:
CPU: Intel Core i5 3570K @ 3.4GHz
RAM: 16GB 1600MHz DDR3
Motherboard: Asrock Z77 Extreme4
Drive: 240GB SATA3 SSD (LM is installed on a 40GB ext4 partition on this drive, the rest of this drive is currently empty; there are some other hard disks installed, if that has any effect)
Graphics: using built in Intel HD4000
Sound: Creative X-Fi XtremeAudio PCI-Express
Other: SATA DVD Burner, Internal SD card reader, ComproDTV TV Tuner
I haven't done anything with drivers as the default install seemed to have everything working in-tact. I have installed VirtualBox (non-free) and Wine, so I don't know whether these have any effect.
I've run Memtest for about half an hour with no errors. Although I haven't been putting the system under any particular load when the freezes have occurred, I've tried putting load on the CPU for a few minutes (running cpuburn), and this hasn't caused a freeze up.
Here's some output after rebooting from a crash.
Please indicate if I should provide any more information.
Thanks in advance for any assistance!
